General Description

The HMC972LP5E is an analog controlled variable gain amplifier composed of two identical voltage variable attenuators in combination with an InGaP HBT gain block MMIC amplifier which operates from 0.5 to 6 GHz, and can be controlled to provide anywhere from 15 dB of gain to 35 dB of attenuation. The HMC972LP5E delivers noise figure of 7.5 dB in its maximum gain state, with output IP3 of up to +28 dBm. The HMC972LP5E is housed in a RoHS compliant 5x5 mm QFN leadless package, and requires no external matching components.
